megaman doesnt get hired bcs he was a dick to a bunch of people in the scene and arrogant as fuck, i think richard lewis even made a video about it.... not sure.
as for dust mouret: hes actually really good bcs u can tell he has watched dozens of demos and he knows all the setups and defaults of each team, what they like to do and stuff so his color casting is pretty good.

If its between dust mouret and a guy like rizc or even pansy, i'll take dust any day of the fucking week.
Hes not the best but hes also not the worst. For NA casters Megaman is quite good and the Blu/DaZeD combo is also good.
